This patchset fixes various issues with perf probe on powerpc across ABIv1 and ABIv2: - in the presence of DWARF debug-info, - in the absence of DWARF, but with the symbol table, and - in the absence of debug-info, but with kallsyms.
Arnaldo, I have moved all patches to use __weak functions. Kindly take a look and let me know if this is what you had in mind. Thanks! - Naveen ---- Changes since v2: The primary change is with the use of __weak functions instead of compiler macros. Along with that, I have also addressed all previous review comments (*). Individual patches have the detailed changelog. Please note that I have dropped the first (kernel) patch from the last series since it has been pushed upstream. This series now only includes the rest of the patches. (*) http://thread.gmane.org/gmane.linux.kernel/1851128 Naveen N.
